Application filed October 23,1919, Serial no; seem? To all whom it may concern:

Be it known that I, ALBERT Gr. BoRoHnR'r,

' residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented a certain new and useful Improvement in Concrete (jonstruction, of whichthe followin is a full, clear, and exact description, reference being had building or in an interior wall. The general object is the provision of a doorway within the building in such a manner that it may constitute a permanent part of the wall and at the same time may provide an air tight and heat-resisting connection to the refrigerator proper. Other objects are to provide a concrete construction for this purpose which shall be economical in construction and strong and tight in use and may have its body portion installed at the time the wall is constructed, the door and the refrigerator itself being readily added and joined afterward.

My invention is hereinafter more fully described 'in. connection with the accompanying drawings, and the essential characteristics thereof are summarized in the claims.

In the drawings, Figure 1 is a front elevation of a wall of a building having my builtin refrigerator door construction; Fig. 2 is a vertical section through the wall and a refrigerator adjacent thereto; Fig. 3 is a section through the concrete frame of the door 1 way; Fig. 4 is a vertical section through the doorway of a refrigerator of adi'fferent type; Fig. 5 is a front elevation thereof;

and Fig. 6 is an enlarged detail section showing the connection between the refrigerator wall and door.

Referring to the drawings, more particularly to Figs. 1, 2 and 3, the numeral 10 designates the outside wall of a building,

illustrated as of brick construction. Within and adjacent to this wall is shown a refrigerator 11 of any suitable type, the one illustrated having the usual double wall construction with inner walls 12 and outer walls 13. The side within the room and remote from the wall 10 may be provided with the usual doors 14 and 15, while a shelf16 located at a convenient height as illustrated, provides a floor for the ice.

This invention relates to the construction 1 My invention is, particularly concerned with a concrete frame 20 located in the wall and forming a tight connection with therefrigerator. In building the wall 10 the masonor other workman, will, upon reachingthe convenient and proper height illustrated,. insert and build into the wall this hollow frame, which will provide an opening from the outside of the wall 10 into the lee compartment of the refrigerator. I

- The frame 20 is cast asoneintegral memher, and may be reinforced by internal metal rods. It is of a depth less than the thickness of the; wall 10 and is provided with horizontal and parallel; outer topandbot-. tom edges 21, but with inclined inner top and bottom edges 22, these edges sloping outwardly. Drippings from the ice being placed in the refrigerator, therefore, will run outwardly to the ground. The inner edgesof the side of theeframe 20 facing out-. wardly are preferably faced at the corners with protecting, angle irons 23 which prevent 'wear or crumbling of the concrete at these exposed points. I

The outer surfaces'of the frame 20 may be recessed as at 30 and in building the wall such recessesare packed with oakum or other filling compound 31 whereby a tight joint between the concrete 20 and thewall v 10 is secured. v

The rear edges of the frame 20 are rabbeted as at 35 and adapted to receive in tight fitting engagement a. rectangular frame 36 screwed or otherwise secured to the wall 13 of; the refrigerator adjacent to the wall 10. Within the frame 36 this wall of therefrigeratoris provided with an; inner door 37 adapted to open outwardly withinYthe frame 20. i

Projecting from the forward edge of the frame 20, andspaced at suitable. intervals aroundits periphery are the threaded ends of bolts 25, having heads embedded within the concrete. A rectangular frame 26, pref-. erably of finished wood, is provided with a plurality of openings corresponding in number to thebolts and in registry therewith,

whereby it may be secured to the concrete frame. Within this wood frame is secured a door 27 adapted to open outwardly on suitable hinges 28.

In Figs. 4, 5 and 6, I have illustrated a door construction for internal walls or partitions, particularly adapted to large refrigerators such as used in shops, stores, etc. In

this type the refrigerator 41 adjoins the interior wall 40, the studding being cut away to form a rectangular opening, and the ends and sides thereof being closed by. suitable headers or strips as at 42. Within this opening is secured a concrete frame 45 similar to the frame 20 except that the top and bottom inner faces are inclined inwardly as illustrated to permit drippings to run into the refrigerator instead of outwardly onto the floor. The frame 45 may be reinforced by iron or steel bars 44, if desired, in any suitable manner, as illustrated in Fig. 6.

The inner edges of the frame 45 are rabbeted laps the wall around the entire periphery of the opening occupied by the frame.

A door 50 may be suitably mounted on hinges 51 within the frame 49 and is adapted to swing outwardly and as in the preceding case be closed against the angle iron binding around'the edges of the concrete frame.

From the foregoing it will be apparent that I have attained the objects desired and provided a strong and tight doorway construction, which maybe readily installed at the time the wall is built, and is convenient in use and pleasing in appearance.

I claim: v

1. The combination, with a wall having an opening, of a concrete frame set in said opening, there being a recess around the outer surface of said frame, packing in said recess making a tight connection between the frame and wall, and a refrigerator making a rigid connection with the inner side face of the frame.

2. In combination, a wall-having an opening therein, a refrigerator adjacent to said wall having means of access in registrywith said opening, a rectangular concrete frame within said opening, the outer surfaces of said frame having recesses therein, packing means within said recesses, a tight joint between the inner face of said frame and the refrigerator wall, a door frame removably bolted to the opposite face, of said concrete frame and a door pivoted thereto.

3. In a refrigerator door construction, the combination of a wall having an opening therein, a concrete frame around said opening, at least one of the inner surfaces of said frame being inclined from the horizontal, a door removably secured to the outer face of said frame, theinner face thereof being in tight engagement against a refrigerator .wall.

therein, a concrete frame around saidopenmg, packlng means between the outer surfaces of said frame and the wall, a doorremovably secured to the outer face of said frame, the inner face thereof being in tight engagement against a wall of the refrigerator having means of access in registry with said opening 6. In a refrigerator door construction a refrigerator having an opening, a concrete frame in tight engagement with the wall around said opening, said frame being our bedded in a wall separate from the refrigerator, and having protecting metal strips at its exposed corners and a .door removably secured to said frame.

7. The combination with a wall having an opening, of a concrete frame set. in said opening, there being a recess around the outer surface of said frame, and packing in, said recess making a tight connection be tween the frame and wall.- i i 8. The combination with a wall having an opening, of a concrete frame set in said opening, there being a recess around the outer surface of said frame, packing in said recess making a tight connection between the frame and wall, a wooden fame removabl bolted to one face of the said concrete, frame, and a closure member pivoted thereto.
